Answer:
u=5.23
Step-by-step explanation:

The hundredths place is where the 5 is.
Look to the right of the hundredths place and determine if the number is 5 or more or if the number is 4 or less.
In this problem, the number to the right of 5 is 1, and 1 is less than 4.
This means you can keep the 5 the same and every number after the 5 becomes imaginary zeroes.
3.95174 becomes 3.95 (rounded to nearest hundredth).
Answer:
21 - q
Step-by-step explanation:
3 * 7 = 21
21 - q = 21 - q
Answer:
X=20; pqr = 130°
Step-by-step explanation:
They key here is to notice that the instructions say that qs bisects pqr, meaning that it evenly cuts it into 2 pieces. So, to find x, you just solve for x in the equation 3x+5=2x+25. Then, you plug it back into either side of the equation, at which point, you should get 65. Since it is half of pqr, just double it to get your final answer of 130°
